The present invention generally relates to novel synthetic methods, systems, kits, salts, and precursors useful in medical imaging. In some embodiments, the present invention provides compositions comprising an imaging agent precursor, which may be formed using the synthetic methods described herein. An imaging agent may be converted to an imaging agent using the methods described herein. In some cases, the imaging agent is enriched in
18
F. In some cases, an imaging agent including salt forms (e.g., ascorbate salt) may be used to image an area of interest in a subject, including, but not limited to, the heart, cardiovascular system, cardiac vessels, brain, and other organs.
本发明通常涉及用于医学成像的新型合成方法、系统、试剂盒、盐和前体。在某些实施例中,本发明提供包含成像剂前体的组合物,该前体可使用本文所述的合成方法形成。成像剂可以使用本文所述的方法转化为成像剂。在某些情况下,成像剂富含18F。在某些情况下,包括盐形式(例如
抗坏血酸盐)的成像剂可以用于成像受试者的感兴趣区域,包括但不限于心脏、心血管系统、心脏血管、大脑和其他器官。
